N2 - The near-infrared absorption spectrum of He2 has been recorded in the range of 12 090-13 300 cm-1 using the optical heterodyne concentration modulation spectroscopy. Fifty-nine He2 spectral lines were assigned to the (1, 0), (2, 0), (3, 1) and (4, 2) bands in the c3Σg+-a3Σu+ system and a non-linear least-squares fitting was performed to get the improved molecular constants for the levels (υ = 1, 3 and 4) in the upper electronic state.
